The present invention provides an attractant for a living organism having a long duration of attracting effect. In a polymer (1) having a structural unit (a) having a carboxyl group and / or a sulfonic acid group as an essential structural unit, the proportion of the structural unit is 20 to 100% by weight based on (1). And 30 to 100 mol% of protons of the acid group are quaternary ammonium cation (I), tertiary sulfonium cation (II), quaternary phosphonium cation (III), tertiary oxonium cation ( IV), a crosslinked product (A) of the polymer (1) substituted with one or more onium cations selected from the group consisting of alkylpyridinium cations (V) and a bio-attractive component (B) It is a biological attractant.
